Scope
1.1These requirements cover Appliance Wiring Material (AWM) in the form of single insulatedconductors，multi-conductor cables，optical fibers，individualinsulated conductors,and fiber opticmembers for use as components in multi-conductor cables.
1.2 The appliance wiring material covered by the requirements of this Standard are solely for use asfactory-installed wiring either within the overall enclosure of appliances and other equipment (internalwiring) or as external interconnecting cable for appliances (external wiring), or for further processing ascomponents in multi-conductor cables.
1.3 These requirements do not cover any wire,cable,or cord types that are presently covered in theNationalElectrical Code (NEC),NFPA 70, and are not intended for installation in buildings or structures inaccordance with the NEC except within the scope of the installation instructions of the end-product forwhich their use is intended.
1.4These requirements cover appliance wiring material with operating temperatures from a minimum60°C (140°F) dry temperature rating and voltage ratings from a minimum 30-volt rating.Conductor sizeranges from 50 AwG to 2000 kcmil Appliance wiring material (AWM) composed entirely of optical fibermembers or electrical conductors in combination with optical fiber members are also covered by theserequirements.
1.5These requirements do not cover the optical performance of any optical-fiber member or group ofsuch members.
1.6 These requirements do not cover constructions which utilize flat, insulated conductors that are notlaid parallel. The requirements for these products are found in the Standard for Flexible Materialslnterconnect Constructions,UL 796F.
1.7 The evaluation of the performance of the semi-conductive polymeric layer described in 5.9 is notcovered by this Standard.
1.8 In addition to these constructions, this Standard establishes guidelines for the evaluation of specialconstructions that, due to their specific end product use, are not required to meet all of the requirementsfor general construction AWM.
1.9 The final acceptance of AWM is dependent upon its use in complete equipment that conforms withthe standards applicable to such equipment.
General
2.1Components
2.1.1 Except as indicated in 2.1.2, a component of a product covered by this Standard shall comply withthe requirements for that component.
2.1.2A component is not required to comply with a specific requirement that:
a) Involves a feature or characteristic not required in the application of the component in theproduct covered by this standard, or
b) ls superseded by a requirement in this standard.
2.1.3 A component shall be used in accordance with its rating established for the intended conditions of use.
2.1.4 Specific components are incomplete in construction features or restricted in performance capabilities. Such components are intended for use only under limited conditions, such as certain temperatures not exceeding specified limits, and shall be used only under those specific conditions.
2.1.5 Polymeric materials evaluated for its intended use, are not prohibited from being used in the insulation and jacket applications indicated in Table 2.1.
